This application is the National Stage filing under 35 U.S.C. 371 of International Application No. PCT/KR2014/011871, filed on Dec. 5, 2014, the contents of which are all hereby incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present invention relates to a mobile device, a wearable device, and a method of providing an interface using the mobile device and the wearable device.

BACKGROUND ART

FIG. 1 is a diagram for an example of a wearable device.

Wearable devices having a display of various shapes are developing. For example, FIG. 1 shows a wearable device 200 having a display unit 220 of a circle form. Yet, a picture generally has a rectangular form of a ratio such as 4:3 or 16:9.

Hence, as shown on the top of FIG. 1, the whole picture can be displayed on the circle display unit 200. Yet, the display unit 220 of the wearable device 200 is relatively small. Hence, as shown on the top of FIG. 1, if the whole picture is displayed on the circle display unit 200, an excessively small picture is displayed.

Meanwhile, as shown on the bottom of FIG. 1, the circle display unit 200 can be filled with a displayed picture. Yet, in this case, a part of the picture is not displayed. And, the picture is not displayed in accordance with the intention of a user.

Hence, it is necessary for the user of the wearable device 200 to edit the picture to make the picture fit the display unit 200 of the wearable device 200. Yet, since the wearable device 200 has the relatively small display unit 220, it is not easy to edit the picture. And, the user can edit the picture using an image editing program of a different device. In this case, it is necessary to consider a size, resolution, and a shape of the display unit 220 of the wearable device 200. Moreover, it is necessary to have a separate processor for transmitting an edited picture to the wearable device 200.

Therefore, it is necessary to have an interface capable of being easily used and processing an intuitive image.

DISCLOSURE OF THE INVENTION Technical Task

An object of the present specification is to provide a mobile device capable of editing an image based on device information of a wearable device and an interaction method between the mobile device and the wearable device. In particular, the object of the present specification is to provide a more enhanced interface for editing and transmitting an image by providing an interface corresponding to a display unit of the wearable device.

In this case, the interface has a shape practically identical to a shape of a display of the wearable device and can be changed based on a change of a relative position of the wearable device for the mobile device.

To further achieve these and other advantages and in accordance with the purpose of the present invention, according to a different embodiment, a wearable device includes a display unit configured to display an image, a communication unit configured to communicate with a mobile device, and a processor configured to control the display unit and the communication unit, the processor, if the mobile device is positioned in the vicinity of the wearable device, configured to transmit device information of the wearable device to the mobile device using the communication unit, the processor configured to display an image received from the mobile device on the display unit.

FIG. 2 is a diagram for configurations of a mobile device and a wearable device according to one embodiment.

A mobile device 100 according to one embodiment of the present specification can include a display unit 120 configured to display an image and receive a touch input, a communication unit 130 configured to communicate with a wearable device 200, a detecting unit 140 configured to detect a relative position of the wearable device 200 for the mobile device 100, and a processor 110 configured to control the display unit 120, the communication unit 130, and the detecting unit 140.

The display unit 120 displays at least one image and can receive a touch input. The display unit 120 can include an LCD (liquid crystal display), a plasma display, or a display of a different type. And, the display unit 120 can include a touch sensor. In particular, the display unit 120 can include a touch sensitive display unit. The touch sensor can be positioned on the display unit 120 or in the inside of the display unit 120. The touch sensor can sense various touch inputs such as a contact touch input or a non-contact touch input including a sliding touch input, a multi touch input, a long-press touch input, a short-press touch input, a drag touch input, a hovering input, and a flicking touch input. Moreover, the touch sensor can sense a touch input inputted by various input tools such as a touch pen, a stylus pen, and the like. The touch sensor can forward a result of sensing a touch input to the processor 110.

The communication unit 130 communicates with the wearable device 200 and can receive device information of the wearable device 200 from the wearable device 200. The communication unit 130 can receive information from at least one external device. The communication unit 130 performs communication via a wired or wireless network using various protocols and can transmit/receive data. For example, the communication unit 130 can use WLAN (Wireless LAN), IEEE 802.11 based wireless LAN communication, Wibro (Wireless Broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), Bluetooth, NFC (Near Field Communication) standard, etc. to access a wireless network. And, the communication unit 130 can access the Internet via a wired/wireless network.

The detecting unit 140 can detect a relative position of the wearable device 200 for the mobile device 100. The detecting unit 140 can include at least one sensor for sensing a position of the wearable device 200. For example, the detecting unit 140 can include an image sensor and/or a proximity sensor. For example, the detecting unit 140 can detect a position of the wearable device 200 via image processing. In order to detect a position of the wearable device 200, the detecting unit 140 can include one or more image sensors and/or proximity sensors. The detecting unit 140 can detect a position of the wearable device 200 using a magnetic field and/or an electric field. For example, the detecting unit 140 can include one or more magnetic field sensors and/or electric field sensors located at a different position. The detecting unit 140 compares values measured by the electric field sensors and/or the magnetic field sensors located at a different position with each other to detect a position of the wearable device 200. The detecting unit 140 can include a touch sensor. The detecting unit 140 senses a touch input caused by the wearable device 200 to sense a position of the wearable device 200.

The detecting unit 140 can sense a position of the wearable device 200 by selectively combining the aforementioned sensing methods. For example, if a distance between the mobile device 100 and the wearable device 200 is equal to or greater than a predetermined distance, the detecting unit 140 senses a position of the wearable device 200 using an image sensor. If the distance between the mobile device 100 and the wearable device 200 is less than the predetermined distance, the detecting unit 140 can detect a position of the wearable device 200 using a magnetic field sensor, an electric field sensor, a proximity sensor and/or a touch sensor. The aforementioned sensors of the detecting unit 140 are an example only. It may use sensors of a different type to determine a relative position of the wearable device 200 for the mobile device 100.

If a side to which the display unit 120 of the mobile device 100 is deployed corresponds to the front side, the sensors of the detecting unit 140 can be deployed to the rear side of the mobile device 100. For example, the sensors of the detecting unit 140 can sense a position of the wearable device 200 at the rear side of the mobile device 100.

The detecting unit 140 can detect a position of the wearable device 200 together with the communication unit 130. For example, the detecting unit 140 can include 2 sensors respectively existing at opposite edges. In this case, the detecting unit 140 measures a distance between the wearable device 200 and the mobile device 100 using the communication unit 130 and determines a position of the wearable device 200 using the sensors of the detecting unit 140.

The mobile device 100 according to the present specification may not require an absolute position of the wearable device 200. In particular, the mobile device 100 according to the present specification may detect a relative position of the wearable device 200 only for the mobile device 100. Yet, the mobile device 100 can obtain the absolute position of the wearable device 200 using a GPS of the wearable device 200.

The processor can control the display unit 120, the communication unit 130, and the detecting unit 140. And, the processor 110 can control other configurations included in the mobile device 100. The processor 110 can execute various applications by processing data of the mobile device 100. The processor 110 can control the mobile device 100 and contents executed in the mobile device 100 based on a command

The wearable device 200 according to one embodiment of the present specification can include a display unit 220 configured to display at least one image, a communication unit 230 configured to communicate with the mobile device 100, and a processor 210 configured to control the display unit 220 and the communication unit 230.

The display unit 220 can displays at least one image. The display unit 220 can include an LCD (liquid crystal display), a plasma display, or a display of a different type. And, the display unit 220 can include a touch sensor. In particular, the display unit 220 can include a touch sensitive display unit. The touch sensor can be positioned on the display unit 220 or in the inside of the display unit 220. The touch sensor can sense various touch inputs such as a contact touch input or a non-contact touch input including a sliding touch input, a multi touch input, a long-press touch input, a short-press touch input, a drag touch input, a hovering input, and a flicking touch input. Moreover, the touch sensor can sense a touch input inputted by various input tools such as a touch pen, a stylus pen, and the like. The touch sensor can forward a result of sensing a touch input to the processor 210. For example, the display unit 220 may have a circle shape or a rectangular shape.

The communication unit 230 communicates with the mobile device 100 and can transmit device information of the wearable device 200 to the mobile device 100. The communication unit 230 can receive information from at least one external device. The communication unit 230 performs communication via a wired or wireless network using various protocols and can transmit/receive data. For example, the communication unit 230 can use WLAN (Wireless LAN), IEEE 802.11 based wireless LAN communication, Wibro (Wireless Broadband), Wimax (World Interoperability for Micorwave Access), HSDPA (High Speed Downlink Packet Access), Bluetooth, NFC (Near Field Communication) standard, etc. to access a wireless network. And, the communication unit 230 can access the Internet via a wired/wireless network.

The processor 210 can control the display unit 220 and the communication unit 130. And, the processor 110 can control other configurations included in the wearable device 200. The processor 210 can execute various applications by processing data of the wearable device 200. The processor 210 can control the wearable device 200 and contents executed in the wearable device 200 based on a command

The mobile device 100 and the wearable device 200 can further include configurations not depicted in FIG. 2. For example, the mobile device 100 and/or the wearable device 200 can further include a memory, a power source, housing, an audio receiving unit, an audio outputting unit, a location determination unit, or an image sensing unit. The image sensing unit can sense an image using visible ray, infrared ray, ultraviolet ray, a magnetic field and/or sound wave.

The aforementioned configurations can be selectively combined according to selection of a manufacturer, or a type of the mobile device 100 and/or the wearable device 200. The configurations can be connected with each other via a bus and can be respectively controlled by the processors 110/210.

Meanwhile, the configuration diagram of the mobile device 100 and the wearable device 200 shown in FIG. 2 corresponds to a block diagram according to one embodiment. Blocks represented as being separated show hardware configuration units in a manner of being logically distinguished. Hence, each of the configuration units of the mobile device 100 can be implemented by a single chip or a plurality of chips depending on the design of the mobile device 100. And, each of the configuration units of the wearable device 200 can be implemented by a single chip or a plurality of chips depending on the design of the wearable device 200.

Meanwhile, the mobile device and the wearable device according to the present specification can be controlled based on various inputs. For example, the mobile device 100 and/or the wearable device 200 can include a physical button and can receive an input from the physical button. And, the mobile device 100 and/or the wearable device 200 can include a voice receiving unit, perform voice recognition based on received voice, and can be controlled based on the voice recognition. Specifically, the voice recognition can be performed in a unit of a syllable, a word, or a sentence. The mobile device 100 and/or the wearable device 200 can be controlled by combining the recognized syllable, the word, or the sentence. The mobile device 100 and/or the wearable device 200 can perform image analysis using an image sensing unit and can be controlled based on an analyzed image. The mobile device 100 and/or the wearable device 200 can include a touch sensing unit and can be controlled based on a touch inputted on the touch sensing unit. Moreover, the mobile device 100 and/or the wearable device 200 can be controlled based on a combination of the aforementioned inputs.

And, operations of the mobile device 100 and the wearable device 200 described in the following can be performed by the mobile device 100 and/or the wearable device 200 mentioned earlier with reference to FIG. 2.

FIGS. 3a to 3c are diagrams for an interface of a mobile device provided according to one embodiment.

Referring to FIG. 3a , a first image 301 is displayed on the display unit 120 of the mobile device 100. A user of the mobile device 100 may want to transmit a part of the first image 301 to the wearable device 200 of the user. For example, the user of the mobile device 100 may want to use the part of the first image 301 as a wallpaper of the wearable device 200.

Referring to FIG. 3b , the user places the wearable device 200 near the mobile device 100. For example, as shown in FIG. 3b , the user may place the wearable device 200 in the vicinity of the rear side of the mobile device 100.

As mentioned earlier with reference to FIG. 2, the mobile device 100 can determine whether or not the wearable device 200 is placed in the vicinity of the mobile device 100 using the detecting unit. For example, if a distance between the wearable device 200 and the mobile device 100 is less than a predetermined distance, the mobile device 100 can determine it as the wearable device 200 is located in the vicinity of the mobile device 100. And, for example, when the wearable device 200 adheres to the rear side of the mobile device 100, the mobile device 100 can determine it as the wearable device 200 is located in the vicinity of the mobile device 100.

If the wearable device 200 is placed in the vicinity of the mobile device 100, the mobile device 100 receives device information of the wearable device 200 from the wearable device 200 using the communication unit. For example, the device information of the wearable device 200 can include at least one selected from the group consisting of a shape, a size, and a resolution of a display unit 220 of the wearable device 200. And, the device information of the wearable device 200 includes a model number and/or a unique number of the wearable device 200. The mobile device 100 can determine at least one selected from the group consisting of a shape, a size, and a resolution of a display unit 220 of the wearable device 200 based on information stored in advance.

Having received the device information of the wearable device 200, the mobile device 100 displays an interface 305 for editing the first image 301 on the first image 301 based on the device information. The wearable device 200 can make the mobile device 100 provide the interface 305 by transmitting the device information of the wearable device 200 to the mobile device 100.

The interface 305 has a form practically identical to the display unit 220 of the wearable device 200. The interface 305 can be changed based on a change of a relative position of the wearable device 200 for the mobile device 100.

For example, as shown in FIG. 3b , if the display unit 220 of the wearable device has a circle shape, the interface 305 of a circle shape can be displayed.

And, the interface 305 can be changed based on a position change changed by a user by moving the wearable device 200 or the mobile device 100 between the wearable device 200 and the mobile device 100. For example, if the wearable device 200 is moved to the upper side in a manner that the user moves a left hand of the user to the upper side, the interface 305 can also be moved to the upper side.

As shown in FIG. 3b , the interface 305 may have a boundary line. And, for example, the first image 301 in the interface 305 may differ from the first image 301 out of the interface 305 in terms of a chroma, brightness, contrast, and/or definition.

The mobile device 100 can provide the interface 305 to a position closest to the wearable device 200. Yet, if the wearable device 200 is placed in the vicinity of the mobile device, the mobile device 100 may provide the interface 305 to a predetermined position. For example, the center of the display unit 120 of the mobile device 100 can be configured as an initial position of the interface 305.

The mobile device 100 can transmit a partial image (e.g., the first image 301 in the interface 305) corresponding to the interface 305 among the first images 301 to the wearable device 200. For example, if a distance between the mobile device 100 and the wearable device 200 is less than a first distance, the mobile device 100 can display the interface 305. And, for example, the mobile device 100 can mirror the first image 301 in the interface 305 to the wearable device 200 after the interface 305 is provided.

After the interface 305 is displayed, if the distance between the mobile device 100 and the wearable device 200 exceeds a second distance, the mobile device 100 can transmit a partial image corresponding to the interface 305 among the first images 301 to the wearable device 200. Hence, a partial image of the first image 301 corresponding to a shape of the display unit 220 of the wearable device 200 is transmitted to the wearable device 200.

As shown in FIG. 3c , having received the partial image, the wearable device 200 can display the received partial image on the display unit 220.

Referring back to FIG. 3b , a user can call out the interface 305 by approaching the wearable device 200 to the mobile device 100. The user can transmit an image preferred by the user to the wearable device 200 by simply moving the wearable device 200 away from the mobile device 100. In particular, the user can copy a picture by simply attaching the wearable device 200 to the mobile device 100 and detaching the wearable device 200 from the mobile device 100. Meanwhile, the mobile device 100 can transmit a partial image to the wearable device 200 based on a separate input as well as the distance between the wearable device 200 and the mobile device 100. For example, if an area in the displayed interface 305 is touched, the mobile device 100 can transmit a partial image of the first image in the interface 305 to the wearable device 200.

Meanwhile, for example, the first image 301 can include a map image. In this case, the mobile device 100 can transmit a geographic coordinate to the wearable device 200 instead of the partial image of the first image 301. In particular, if the first image 301 corresponds to a map image, the mobile device 100 can transmit a geographic coordinate corresponding to a position of the interface 305 to the wearable device 200. Having received the geographic coordinate, the wearable device 200 may start to guide a way based on the received coordinate.

When the mobile device 100 provides the interface 305 to the wearable device 200, the mobile device can provide auditory feedback or tactile feedback to the wearable device 200 together with the interface 305.

The operations of the mobile device 100 and/or the wearable device 200 mentioned earlier with reference to FIGS. 3a to 3c can be combined with each other. In this case, the operations can be selectively combined with operations of the mobile device 100 and/or the wearable device 200 to be explained in the following with reference to FIGS. 4 to 12.

FIG. 4 is a diagram for an example of moving an interface according to one embodiment.

Referring to FIG. 4(a), the wearable device is positioned at the rear side of the mobile device 100 and the interface 305 is displayed on the first image 301 of the mobile device 100. In this case, a user may want to transmit a different part of the first image 301 to the wearable device.

In this case, as shown in FIG. 4(b), the user may move the wearable device 200 in down direction. As a result, a relative position between the mobile device 100 and the wearable device 200 is changed. The mobile device 100 moves a position of the interface 305 based on the change of the relative position. Hence, as shown in FIG. 4(b), the interface 305 is moves to the down direction of the mobile device 100.

In FIG. 4(b), the position of the interface 305 is moved to the down direction of the mobile device 100 by relatively moving the wearable device in down direction for the mobile device 100. Yet, the user can also move the position of the interface 305 to the down direction of the mobile device 100 by relatively moving the mobile device 100 in up direction for the wearable device 200.

The movement of the interface 305 shown in FIG. 4 is just an example only. The user can move the interface 305 in any direction by changing a relative position of the wearable device for the mobile device 100. The operations of the mobile device 100 and/or the wearable device 200 mentioned earlier with reference to FIG. 4 can be selectively combined with operations of the mobile device 100 and/or the wearable device 200 explained in FIG. 3a and FIGS. 5 to 12.

FIG. 5 is a diagram for an example of magnifying an interface according to one embodiment.

Referring to FIG. 5(a), the wearable device 200 is positioned in the vicinity of the rear side of the mobile device 100. In particular, the interface 305 is displayed on the first image 301 based on a shape and a size of the display unit 220 of the wearable device 200. In this case, a user may want to transmit more partial images to the wearable device 200.

Referring to FIG. 5(b), the user moves the wearable device 200 to increase a distance between the mobile device 100 and the wearable device 200. The mobile device 100 can increase a size of the interface 305 based on the increased distance. For example, if a position of the interface 305 is maintained for more than prescribed time, the mobile device 100 can change the size of the interface 305 based on the distance between the mobile device 100 and the wearable device 200. And, if the distance between the mobile device 100 and the wearable device 200 is maintained for more than prescribed time after the size of the interface 305 is changed, the mobile device 100 can transmit a first image 301 corresponding to the changed interface 305 to the wearable device 200. Yet, the mobile device 100 may operate in a mode for changing the size of the interface 305 based on an input inputted on a sub interface described in the following. The mobile device 100 can transmit a first image 301 in the changed interface 305 to the wearable device 200 based on the input inputted on the sub interface described in the following.

Referring to FIG. 5(b), the distance between the mobile device 100 and the wearable device 200 is changed by moving the wearable device 200. Yet, the distance between the mobile device 100 and the wearable device 200 can also be changed by moving the mobile device 100 and the size of the interface 305 can be changed based on the changed distance.

In this case, the distance change changed by moving the wearable device 200 and the distance change changed by moving the mobile device 100 can be performed as a different operation. For example, the mobile device 100 can change a display size of the interface 305 based on a changed distance only when the distance between the mobile device 100 and the wearable device 200 is changed by moving the wearable device 200.

The operations of the mobile device 100 and/or the wearable device 200 mentioned earlier with reference to FIG. 5 can be selectively combined with operations of the mobile device 100 and/or the wearable device 200 explained in FIG. 3a , FIG. 4 and FIGS. 6 to 12.

FIG. 6 is a diagram for an example of magnifying an image according to one embodiment.

As mentioned earlier in FIG. 5(b), the size of the interface 305 can be changed based on the distance between the mobile device 100 and the wearable device 200. Yet, a display size of the first image 301 can also be changed based on the distance between the mobile device 100 and the wearable device 200.

Referring to FIG. 6(a), the wearable device 200 is positioned in the vicinity of the rear side of the mobile device 100. In particular, the interface 305 is displayed on the first image 301 based on a shape and a size of the display unit 220 of the wearable device 200.

In this case, a user may want to magnify the first image 301. Referring to FIG. 6(b), the user increases the distance between the mobile device 100 and the wearable device 200 by moving the mobile device 100. The mobile device 100 displays the first image 301 in a manner of magnifying the first image based on the increased distance.

In particular, if the distance between the mobile device 100 and the wearable device 200 is changed due to the movement of the mobile device 100, the mobile device 100 changes a display size of the first image 301 based on the changed distance. For example, the mobile device 100 can magnify the first image 301 on the basis of a position at which the interface 305 is displayed.

Meanwhile, although the distance between the mobile device 100 and the wearable device 200 is changed due to the movement of the wearable device 200, the first image 301 can also be magnified.

And, if the distance between the mobile device 100 and the wearable device 200 is maintained for more than prescribed time after the size of the first image 301 is changed, the mobile device 100 can transmit a first image 301 corresponding to the interface 305 to the wearable device 200. Yet, the mobile device 100 may operate in a mode for changing the size of the first image 301 based on an input inputted on a sub interface described in the following.

The mobile device 100 can transmit a first image 301 in the interface 305 to the wearable device 200 based on the input inputted on the sub interface described in the following.
